Validity--$100
The extent to which a researcher
can generalize findings to the
population
answer
Validity--$200
The extent to which a researcher
can draw a single, unambiguous
conclusion from the results
answer
Validity --$300
A study is said to be _______ when
an extraneous variable is allowed
to vary along with the independent
variable.
answer
Validity --$400
An ______ variable is a variable
that is not being directly studied,
but has the potential of changing
along with the independent
variable.
answer
Validity -$500
Although tight control over
extraneous variables gives you
high levels of _____, it may result
in low levels of _____.
answer
Strategies & Designs--$100
The goal of this research strategy
is to describe a variable as it exists
naturally.
answer
Strategies & Designs --$200
The goal of this research strategy
is to describe the relationship
between two variables as they
naturally occur in the environment.
answer
Strategies & Designs --$300
A researcher joins a religious cult in
order to observe the behaviors of
the members. The researcher is
using _____ observation.
answer
Strategies & Designs --$400
This type of research design can
be useful for studying unusual
clinical cases such as brain
injuries.
answer

A researcher systematically varies the
amount of caffeine in cola (0, 10, and
20 mg) and observes that his
participants’ anxiety levels increase as
caffeine amount increases. The 0-mg
condition is called the __________.
answer
Frequency Distributions--$100
The simplest frequency distribution
consists of these two columns.
answer
Frequency Distributions --$200
The shape of a _____ distribution
is perfectly symmetrical.
answer
Frequency Distributions --$300
This is the appropriate type of chart
(or visual) for discrete data.
answer
Frequency Distributions --$400
These two types of charts
appropriately represent data from
continuous variables.
answer
Frequency Distributions --$500
A mathematical procedure for
estimating a value that is located
between two known values.
answer
Descriptive Stats--$100
A statistical measure that
determines a single value that
accurately describes the typical
score of a distribution.
answer
Descriptive Stats--$200
This measure of central tendency is
the score at the 50th percentile.
answer
Descriptive Stats --$300
This measure of variability
measures the average distance
between scores and the mean.
answer
Descriptive Stats --$400
This measures the average of the
squared distances from the mean.
answer
Descriptive Stats --$500
In order to calculate this, take the
square root of the population
variance.
answer
Grab Bag--$100
The type of correlation that
indicates an inverse relationship
between two variables.
answer
Grab Bag--$200
